A built trans first off. Twin turbo kit to go behind your stocker. EFI Live or H&S tunning.
A set of 50% over injectors and keep the pulse width down and save the engine.
And lift pump is a must.

I agree built trans would be a start with that tuning. Turbo upgrade cuz Egts get unreal at anything above level 3, maybe EFI tuning. Lots of choices, depending on how deep your pockets are..

For a great everyday driver/ tow rig/ weekend warrior go with twins and be done with it.
A II or MPI turbo kit that uses stock turbo will be more than fine.

well depending on what you want EFI, lift pump, tranny, n exhaust can run you to around almost 550hp before the stock turbo gets out of map
